Abstract

PURPOSE:To execute a secure transmission without deleting transaction data by storing data when the transmission of the transaction data is not normally executed and reading and transmitting data from a memory means when the data transmission cannot be executed. CONSTITUTION:When a fault exists at the communicating line between a cluster controller 1 and a storing controller 4, it is discriminated that a transmission error is present. In such a case, a CPU 10 stores the transaction data to the non-transmitting transaction data memory area 122 of a RAM 12 and adds the number of the counting of a non-transmitting transaction data counter 121 by 1 only. Thereafter, when the data transmission is executed from a host computer 3, the transaction is established, the CPU 10 discriminates that the transmission error is absent, the number of the counting of the counter 121 is checked. When the number of the counting is not 0, the non-transmitting transaction data are read from the area 122 and transmitted to a storing controller 4. The reading is executed by the last-in first-out system.

Description

[Detailed description of the invention] [Industrial application field 1 This invention relates to a card authentication & T terminal group management device 22 (hereinafter referred to as "T terminal group management device 22").

(referred to as a cluster controller), a plurality of card authentication terminal v devices are connected, and the card authentication data transmitted from any of the card authentication terminal devices is transmitted to the host computer, and the host computer determines whether the transaction is possible or not. The card authentication terminal group control 1! receives the transaction information and transmits the result of the transaction to the corresponding card authentication terminal device, and also transmits the transaction data of the transaction authenticated by the host computer to the store controller! I! Regarding equipment.

[Prior art] As is well known, as credit cards become more popular, CAT
A card authentication terminal device called a credit authorization terminal has been put into practical use. Also,
Recently, a raster controller has been provided to manage a plurality of card authentication terminal devices and to mediate data transmission between the CAT, the host computer, and the store controller. Here, the host computer performs credit card authentication, and is installed at a credit card company, for example. The store controller aggregates transaction data and is installed within the store, for example. Card authentication data including transaction data such as card data, product code, and amount data input from the CAT is transmitted online to the host computer via the cluster controller and processed in real time by the host computer. If the host computer determines that the transaction is possible, the cluster controller transmits the transaction data online to the store controller.

[Problems to be Solved by the Invention] By the way, in the conventional cluster controller, when a transaction is transmitted from the cluster controller to the store controller, the store controller does not operate if there is a failure in the communication line or for inspection, etc. When the system is stopped, there is a problem in that the transaction data that should be transmitted is lost.

Therefore, the present invention was made to solve the above-mentioned problems, and its purpose is to provide a raster controller that prevents transaction data from being lost even if data transmission is not performed normally. shall be.

[Means for Solving the Problems] The cluster controller of the present invention has a storage means for storing transaction data, and a transaction data aggregation means, at least transmitting transaction data of transactions determined to be transactable by the host computer. a transmission means for determining whether or not the data transmission was performed normally each time the transaction data is transmitted by the transmission means; Control means controls to write the transaction data in the storage means in response to the determination, and to read the transaction data from the storage means and transmit it by the transmission means when the data transmission by the transmission means becomes possible. It is composed of:

[Operation] In this invention, when the transaction data is not transmitted normally to the transaction data aggregation means, the transaction data is stored in the storage means and can be transmitted back to the transaction data aggregation means. When this occurs, the transaction data is read out from the storage means and transmitted, so that the transaction data is reliably transmitted to the transaction data aggregation means without being lost.

It's up to you to compile the data.

FIG. 3 is a schematic block diagram showing the electrical configuration of the cluster controller 1 shown in FIG. 2. In FIG. 3, the cluster controller 1 has a CF) IJ10b<installation number. A ROM 11, a RAM 12, a store controller side transmission section 13, an upper side transmission section 14, and a lower side transmission section 15 are connected to CPIJlo.

The ROM 11 stores an operating program for the CPU 10 based on a flowchart as shown in FIG. The RAM 12 includes a storage area as shown in FIG. 4, which will be explained later. The store controller side transmission unit 13 mediates data transmission between CPLJlo and the store controller 4. The upper side transmission section 14 is the CPU1

It mediates data transmission between the two.

FIG. 4 is an illustrative diagram showing a transaction data message transmitted from the cluster controller 1 to the store controller 4.

In FIG. 4, the transaction data message 20 consists of a sales/cancellation code indicating sales or profits, the company code of the card company, the customer's membership status, the transaction amount, the number of payment splits, and the store number.

FIG. 5 is an illustrative diagram showing the storage area of the RAM 12 shown in FIG. In FIG. 5, the storage area of RAMI2 includes an unsent transaction data counter 121 and an unsent transaction data storage area 122. The unsent transaction data counter 121 is an area that stores the number of transaction data stored in the unsent transaction data storage area 122.

The unsent equal data storage area 122 is an area for storing transaction data when the transaction data is not transmitted normally to the store controller 4. The unsent transaction data storage area 122 contains, for example, 100
transaction data can be stored. Once the transaction data stored in the untransmitted transaction data storage area 122 is successfully transmitted to the store controller 4, it is deleted.

FIG. 1 is a flow diagram for explaining the operation of an embodiment of the present invention. Next, the operation of one embodiment of the present invention will be described in detail with reference to FIGS. 1 to 5.

It is assumed that there is no untransmitted transaction data at the start of operation. The CPU 10 sets the unsent transaction data counter 121 to O in step 81 (abbreviated as Sl in the figure). Subsequently, in step S2, the process waits until data is transmitted from either the CAT 2 or the host computer 3. The CAT 2 transmits, for example, a card authentication request message containing transaction data such as card data, product code, amount data, etc., and the post computer 3 transmits, for example, a transaction permission message indicating whether or not the transaction is possible. In response to data transmission, the CPU 10 checks where the transmission source is in step S3. This check of the sender is performed, for example, based on the sender identification code included in the transmitted message. Here, it is assumed that the card authentication request message is transmitted from CAT2. In step S4, the CPU 10 edits the transmitted message and sends the edited card authentication request message to the host computer 3. Then, the process returns to step S2.

The host computer 3 determines whether or not a transaction is possible based on the card authentication request message transmitted from the cluster controller 1, and transmits a transaction permission message indicating the result to the cluster controller 1.

In this way, it is possible to trade 6T from the host computer 3.
When the IA statement is transmitted, C of cluster controller 1
In step S5, the PU 10 edits the transmitted message and transmits the edited transaction permission message to the corresponding CAT 2. Subsequently, in step S6, the CPU 10 determines whether or not the transaction has been completed based on the transaction acceptance message transmitted from the host combination. Here, if the transaction has been established, the process proceeds to step S7, and if the transaction has not been established, the process returns to step S2.

In step S7, the CPU 10 immediately transmits transaction data for the completed transaction to the store controller 4. In this way, since transaction data is immediately transmitted to the store controller 4 and used as the store controller, transaction data can be easily aggregated in a short time. Furthermore, since the cluster controller 1 and the roller 1 do not need to have an aggregation function, they can be provided at low cost.

Subsequently, the CPU 10 proceeds to step S8.

Determine whether there is a transmission error. Here, CPL
For example, when receiving a response from the store controller 4 indicating that the reception of the transaction data has been completed, llo determines that the transaction data has been successfully transmitted. therefore,
If there is a failure in the communication line between the cluster controller 1 and the store controller 4, or if the store controller 4 has stopped operating, it is determined that a transmission error has occurred. In this case, the CPtJ 10 stores the transaction data in the unsent transaction data storage area 122 of the RAM 12 in step 813, and in step 31
4, the count number of the unsent transaction data counter 121 is incremented by 1 (). Then, the process returns to step S2.

Thereafter, if data is transmitted from the computer 3 and a transaction is completed, transaction data of the completed transaction is transmitted from the cluster controller 1 to the store controller 4. At this time, step S8
If the CPU IO determines that there was no transmission error, the count number of the untransmitted transaction data counter 121 is checked in step S9. If the count is 0, there is no unsent transaction data, so the process returns to step S2.

On the other hand, if the count is not O, unsent transaction data is read from the unsent transaction data storage area 122 and transmitted to the store controller 4. This succession of unsent transaction data is caused by, for example, a last-in, first-out method in which the most recently stored transaction data is read out first.Next, in step 811, it is determined whether or not there is a transmission error, and if there is a transmission error, However, if there is no transmission error, the transmitted transaction data is deleted from the unsent transaction data storage area 122, and then, at step 812, the count number of the unsent data counter 121 is decremented by 1. , step S
Return to 9. Repeat steps 89 to 812.

When all unsent transaction data has been transmitted to the controllers 0-4, the process returns to step S2.

When the transmission is completed normally, the stored transaction data is erased, so the RAM 12
The storage capacity is small.

[Effect of the invention j As described above, according to the present invention, if the transaction data is not transmitted normally to the transaction data aggregation means, the transaction data is stored in the storage means and transmitted to the transaction data aggregation means. As soon as data transmission becomes possible, the transaction data is read out from the storage means and transmitted, so the transaction data is not lost and is reliably transmitted to the transaction data collection a1 means.
